To all whom it may concern:

Be it known that I, RAYMOND Anoniem a citizen of the United States, residing at Redmond, in the county of Deschutes and- State of Oregon, have invented certain new and useful Improvements in Gasoline En# gines, of which the'following is a specification.

This invention is in the way of a gasoline engine, and the object is to provide a light, durable engine of very simple construction. Another object is to eliminate the water cooling system, thus having a positive and more eiiicient engine in all weather conditions. A further object is to provide an engine with swinging or pivoted cylinders and with connecting rods rigidly joined to the piston heads, thereby keeping the pistou in direct line with the crank shaft at all times and thus eliminating friction and developing more power.

In the drawing Figure 1 is a longitudinal vertical section;

Figure 2 is a front elevation;

Figure 3 is a transverse vertical section through a cylinder, A showing the piston on the up stroke;

Figure 4 is a side elevation;

Figure 5 is a detail of theftiming cylinder;

Figure 6 is a detail of the timing cylinder drive; y

Figure 7. is a detail of the cylinder and pivot strap.

In carrying out this invention, I provide a stationary cylindrical case 1,-the inner periphery thereof tapering to the rear as shown at 2. Bolt holes 3 are provided at the forward end, and an insulated brass ring 4 sets in a groove 5 at the rear end, and a slot 80 is cut in the said case, for a purpose to be later explained. Cylinders 6 are releasahly and pivotally strapped to the case 1, the said cylinders having curved arms 7 their ends terminating in the lugs 8. Bolt holes 9 are cored in the lugs 8, said holt holes 9 registering with bolt holes 10 in the ears 11 of the straps 12, thus forming means for releasably strapping the cylinders 6 to the case 1 through bolts inserted through said holes. Oil grooves 13 are formed in the arms 7. Oil dischargerports 14 connect with the grooves 13 to permit oil to run over the sides of the cylinders 6.l

Ports 16 which serve the secondary feed pipes 29, the spark plugs 30 and the exhaust pipes 3l, are provided in the head of the cylinders 6, saidlports registering with 'elliptic ports 16 of the case 1.

y Pistons 17 carrying rings 18, slidingly engage the inner peripheries of the cylinders 6. ArmsV 19 are cast in ythe pistons 17. The upper ends of connecting rods 20 are rigidly joined to the arms 19 of the pistons 17, while the lower ends terminate in the bearings 21, and Jle said bearings 21l engage a crank shaft valve 23 is provided, its periphery tapering to correspond with the inner periphery of the case 1, and is slidingly mounted in the said case 1. Upon the periphery of the timing cylinder 23, and to the rear of the same gear teeth 24 are cut diagonally, for a purpose to loe later explained. `Within the forward end of the case 1, a ball bearing i race 25 is slidingly mounted;V and the ball hearings of the said race engage the for-V ward end of the timing cylinder 23. A holt 26 is passed through the holes 3 of the case 1. The bolt 26 engages a sleeve 27, carrying a spring 28, which bears upon the `ball bearing race 25, thus tending to keep the timing cylinder 23 frictionally engaged with the inner periphery ofthe case l, yet permitting the said timing cylinder 23 -to slip forward upon expansion. Within the timing cylinder 23 are mounted, relatively to the position of thecylinders 6, the secondary feed pipes 29, the spark plugs 30, and the exhaust pipes 31. The ends 32 of the several branches of the main feed pipe 33 pass through the upper section 43 of the supports 40, 41 and 42, and are secured in the upper portion of the wall of the casing 1, and so spaced as to communicate with the secondary feed pipes 29 at the proper times. The ends 34 ofthe branches of the main exhaust pipe 35 pass through the upper section 43 of the supports 40, 41 and 42, and are secured in the upper portion of rthe wall of the casing 1, and so spaced as to communicate with the eXhaustp'ipes 31 which coinmunicate with the cylinders 6 upon the up strokes of the pistons -17 after the explosions. The spark plugs 30 yfollow'in rotation one on every quarter section around the inner peripheryvof the timing cylinder 23, lout not longitudinally as shown in Figure 1. The wires 36 of the said spark plugs 36,

are run to the rear of the timing cylinder 23, and are held securely thereto by means of insulated clamps 37. The end 38 of the A revolvingtiming cylinder or rotary said wires are turned outwardly so as to frictionally engage the brass ring 4 in the case 1. The said brass ring 4 has an insulated connection 78 withV the battery-wire 39, thus keeping the spark plugs 30 constantly charged with electricity and rcausing them to function at the proper times. The front and rear ends of the timingcylinder 23 and the case 1 are open, to give passage to a constant flow .of air, thus keeping the timing cylinder 23 alwayslcool. The engine supports 40, 41 and 42 are divided into sections. The upper section 43 of the .supports 40, 41 and 42 is cast in onepiece, and serves as part of the enginehousing 44, and also as a bearing shell for the case 1. The said section 43 has grooves 45 to accommodate the straps 12 andl keep them in line with the piston bearings 21. Lugs 46, corresponding to lugs 49 of the section 47, are cast on the upper portion of the section A43 to provide means for securing .it to the section 47 of the supports 40, 41 and 42. The'middle sections 47 of the supports 4Q, 41 vand 42 carry in their upper portions bearing recesses for the case 1, while the lower portion carries the upper half of the crank shaft bearings 48. Bearings 49 are cast on Ithe section 47 lof the support 42`to provide means for journaling the vertical idler `shaft 67 of the timing cylinder drive 50. 'llearing recesses 5l and openings 52 are provided the said section 47 of the support 42, for the shafts and gears of the timing cylinder drive 50. Lugs 53 corresponding to Vlugs v54,l of the section 55 are cast on the lower portion ofthe section 47 to provide means .for securing it to the Section 55 of .the Supports 4.0. 4 1 and 42. Braced lugs 56 are castfor'i` the sidesof the Sections '.47' 0f .the SHPPQITS 49.5 4l @ed 42, t0 provide means for securing the said supports to the frame of a. machine. The secf tions 55 of the supports 40, 41 42 carry in their upper portions the lower lialf of the crank shaft bearings 48. semi-circular hole 57 is cored the section`55 ofthe support 41 to permit oil torun from` one compartment tothe other. The section 55 of the support 42 houses an oil pump 58 and is cast' in two sections. Lugs 59 are cast along' the split surface of the 'Section 55 of the support .42'to provide for means for bolting. same together. An oil inlet 60 is provided at thev side of the pump 58, while an outlet 61 is provided atthe bottom of the said pump. The outlet 4V61 of the pump 58 communicates withl the bottom of the radiator by means of a pipe. Pipes 62 having a series of nozzles 63 are connected to the upper portion of the radiator. VThe noz# zles 63 pass through the sides of the housing 44 and are lin line with the oil grooves 13 of the cylinders 6. The sheet metal housing 44 is lmade in sections; Vthe 4lower sections being provided with petcocks 76 fory drain# ing purposes. A spur gear l64 is mounted on' the crank shaft 22 atV the rear end. The spur gear 64 meshes with an idler 65. The Saidlidlerhas Va .bevel .gear 66 formed on its side, which drives a vertical idler shaft 67 by means of a bevel gear 68 which passes the one end of which is j'ournaledmin oneY of thebearing recesses 51, and the other end is journaled in the gear housing 7 The gear 70 is mounted `upon a 'shaft 72, the one end of which is journaled in one of the :bearing recesses 5l, While the other end journaled in the gear housing 74. A gear 77 mounted at the side of the pump 58 and connected therewith meshes withthe gear 64 mounted on the crank. shaft 22. A fiy wheel 79 is mounted on the crank shaft 22 at the rear end.

In operation, the cylinder being posi- L tioned as shown in Figure 1, cylinder'wA Will exhaust upon the up stroke. Cylinder D will be charged with ga'sbn the down stroke. Cylinder B is firing, cav-using `it to make thea-down stroke. yCylindery C lwill compress the gas on the up stroke. Cyl/inder C follows cylinder B' in firing, after which cylinder D fires, being followed by cylinder A. An electric current passing through the battery wire 39 vkeeps the ringV 4 charged with electricity. The ends 38of the spark plug wires 36 frictionally engage the ring 4, thus keeping the spark plugs'3() charged with elect-ric'it'y.l The Vgear "ratio of the timing cylinder drive V50 is'two to one, the crank shaft "22V making two com# plete revolutions to the timing cylinders one revolution.v The diagonally cut teeth 24 on the timing cyli'i'ider` v23 and on the gear have a tendency towork the said timing cylinder forward, thus permitting it towork with the greatest eiiciency,'whether the timing cylinder is rcold and'contracted, or warm and expanded. The spring 28, bearing upon the ball bearing race 25, keeps the periphery of the timing cylinder 234 frictionarlly engaged with the inner periphery of the case 1, allowing the Atiming cylinder 23 to slip forward just enough to take 'care ofthe eX- pansion of ythey said timing cylinder. 'A constant iow of air passing'thrugh the in# side of the timing icylinderi'23" keeps it cooled. The cylinders'6 are cooled yby oil pumped out .of the housing 444by the oil pump 58, and forced through a radiator into il l) lll) ifo

the pipes 62 and through the nozzles 63, Which terminate at the side of the case 1, permitting the oil to flow into the grooves 13 and over the sides of the case 1. While I have herein described a certain specific manner and method of constructing and assembling the elements of my invention, it is understood that I may vary from the same in minor details, not departing froml the spirit of my invention, so as best to construct a practical device for the purpose intended, as defined in the appended claims.
